Malignant Melanoma – 3rd Most Common Skin Cancer
Malignant melanoma is the third most common skin cancer and the most dangerous. Melanoma originates from the cells in the skin that produce pigment (color) called melanocytes. For this reason, most melanomas are usually brown, black or dark blue in color, however, some melanomas may be tan, pink or red. Untreated melanoma has a high propensity to metastasize to your lymph nodes, liver, lungs, and brain. However, with early detection and treatment, most lesions can be cured. A skin exam by one of Front Range Dermatology Associates’ highly trained providers is a great step in preventing life-threatening melanoma skin cancer. Call today to schedule.
